We developed a barcode scanning system in .NET that targets the compact framework and smart devices. One of our clients purchased a MC92NO-G handheld that is running WinCE7 (build 2864) as installed by the vendor. When attempting to run our application on this device we seem to have compatibility errors between the System.Data.SqlServerCe.dll we target in our .NET application and the one on the device. For instance we are running into random FormatException issues where none should arise (and do not on other devices or emulators).
 
Is there a developer resource for targeting this OS on this device? Perhaps the proper SQL DLLs to match what comes pre-installed on the device? Any help would be appreciated.
